In Kentucky, child support ends when the child turns 18 under KRS 403.213. If the child is still enrolled in high school at age 18, support continues through the end of the school year in which the child turns 19. Kentucky does not require parents to fund college expenses unless both parties voluntarily agree. Effective July 1, 2025, Kentucky doubled the maximum combined income threshold from $15,000 to $30,000 per month and lowered the modification threshold from 15% to 10% under KRS 403.212.

When Does Child Support End in Kentucky Under KRS 403.213
Child support in Kentucky terminates when the child reaches age 18, the legal age of emancipation under KRS 403.213(3). Kentucky law treats the 18th birthday as the default cutoff date, making Kentucky one of 37 states that use age 18 rather than 19 or 21 as the child support termination age. The obligation ends automatically on the child's 18th birthday unless one of several statutory exceptions applies, including ongoing high school enrollment, disability, or early emancipation through marriage or military service.
The paying parent (obligor) should not simply stop payments without confirming that termination conditions are met. Under KRS 403.213, failure to pay court-ordered child support remains enforceable even after the child turns 18 if arrearages exist. Kentucky courts can enforce back child support obligations for up to 15 years after the child reaches the age of majority. Any unpaid balance as of the child's 18th birthday does not vanish; the custodial parent can pursue enforcement through wage garnishment, tax intercept, or contempt of court proceedings.
Parents who want formal confirmation that their obligation has ended should file a motion to terminate child support with the Kentucky Circuit Court in the county where the original order was entered. The filing fee for a motion to modify or terminate child support in Kentucky ranges from $115 to $250 depending on the county. As of March 2026, verify the exact amount with your local Circuit Court Clerk.
High School Extension: Child Support Beyond Age 18 in Kentucky
Kentucky extends child support past age 18 if the child is still enrolled in high school, continuing payments through the end of the school year in which the child turns 19 under KRS 403.213(3). This extension is automatic and does not require a separate court filing. The high school extension applies to both public and private high school enrollment, including accredited home school programs recognized by the Kentucky Department of Education.
The extension has a hard cap at the conclusion of the academic year in which the child turns 19. Even if the child has not yet graduated, child support payments cease at the end of that school year. For example, a child who turns 19 in January 2026 would receive support through approximately May or June 2026, depending on the school district's academic calendar. A child who turns 19 in July would have already completed the school year, and support would end at 19 without further extension.
The paying parent bears the responsibility to verify the child's enrollment status. Kentucky courts allow either parent to request documentation proving ongoing high school enrollment. If the child drops out of high school before turning 19, child support terminates on the date of withdrawal, not at the end of the school year.
Early Emancipation: When Child Support Ends Before Age 18
Kentucky law terminates child support before the child's 18th birthday under four specific circumstances defined in KRS 403.213. Each of these events automatically ends the support obligation without requiring a court hearing, though the paying parent should file documentation with the court to formally close the case.
- Marriage of the child: When a minor marries with parental consent (permitted at age 17 in Kentucky under KRS 402.210), child support terminates immediately on the date of marriage
- Active military service: Enlistment or induction into the United States Armed Forces emancipates the child and ends child support on the date of entry
- Death of the child: Support terminates on the date of death, though the estate may pursue any arrearages owed up to that date
- Court-ordered emancipation: A minor who can demonstrate financial self-sufficiency may petition for a declaration of emancipation, ending child support upon the court's order
Parents should note that simply moving out of the custodial parent's home does not constitute emancipation in Kentucky. The child must meet one of the four statutory conditions listed above. A 17-year-old living independently with a full-time job is not automatically emancipated unless a court grants a formal emancipation order.
Child Support for Disabled Children in Kentucky
Kentucky courts may extend child support beyond age 18 or 19 for children with disabilities that prevent self-sufficiency, with no upper age limit under KRS 403.213. The disability must have existed before the child reached the age of majority, and the child must be wholly dependent on parental support for daily living needs. Courts evaluate each case individually, considering the nature and severity of the disability, the child's capacity for employment, and the financial resources of both parents.
To obtain extended child support for a disabled adult child, the custodial parent must file a motion with the Kentucky Circuit Court before the child's 18th birthday or before the existing order expires. The petition must include medical documentation establishing the disability, evidence of the child's inability to support themselves, and a proposed support amount based on the child's ongoing needs. Kentucky courts consider the availability of government benefits such as Supplemental Security Income (SSI), which pays a maximum federal benefit of $943 per month in 2024, when calculating parental obligations.
The paying parent retains the right to petition for modification or termination of the extended order if the child's condition improves or if the child becomes eligible for sufficient government assistance. Courts review these cases periodically to determine whether continued parental support remains necessary.
Does Kentucky Require Child Support for College
Kentucky law does not require either parent to pay for a child's college education or extend child support during post-secondary enrollment. No Kentucky statute authorizes a court to order college tuition, room and board, or related expenses as part of a child support obligation. This places Kentucky among the majority of states (approximately 35 of 50) that treat college support as a voluntary matter rather than a legal obligation.
However, parents may include college expense provisions in a separation agreement or property settlement agreement during the divorce process. Under KRS 403.180, separation agreements that are incorporated into a divorce decree become enforceable court orders. If a parent agrees in writing to contribute to college expenses and the court approves the agreement, failure to pay can result in contempt of court proceedings, wage garnishment, or other enforcement mechanisms.
Parents negotiating a divorce settlement should carefully consider college support provisions because once the child support obligation ends at age 18 or 19, no mechanism exists to compel the other parent to contribute to higher education costs. Common approaches include specifying a maximum dollar amount per semester, limiting support to in-state public university tuition (averaging approximately $12,000 per year at Kentucky public universities in 2025-2026), or establishing a percentage split based on each parent's income at the time of enrollment.
How to Modify or Terminate Child Support in Kentucky
Kentucky requires a substantial change in circumstances to modify an existing child support order under KRS 403.213. Effective July 1, 2025, Kentucky lowered the modification threshold from a 15% change to a 10% change in the calculated support amount under amended KRS 403.212. This means a parent can now request modification when the recalculated amount differs by just 10% from the current order, making modifications more accessible for Kentucky families.
To file for modification or termination, the requesting parent must submit a motion to the Kentucky Circuit Court in the county where the original order was entered. The process involves the following steps:
- Complete the Motion to Modify Child Support form available from the county Circuit Court Clerk's office or the Kentucky Court of Justice website at kycourts.gov
- Pay the filing fee, which ranges from $115 to $250 depending on the county (as of March 2026; verify with your local clerk)
- Serve the other parent with notice of the motion at least 10 days before the scheduled hearing
- Attend the hearing and present evidence of the changed circumstances, including updated income documentation, proof of the child's emancipation event, or evidence of the child reaching the age of majority
- Obtain the court's written order modifying or terminating support
Common grounds for modification beyond the child reaching age 18 include a significant increase or decrease in either parent's income, a change in the child's medical needs, a change in the parenting time schedule, or the child becoming self-supporting. Under the 2025 amendments to KRS 403.212, the combined monthly income cap has doubled from $15,000 to $30,000, which may result in higher support amounts for families where both parents earn above the previous threshold.
2025 Kentucky Child Support Law Changes
Kentucky enacted significant amendments to KRS 403.212 effective July 1, 2025, under 2024 Kentucky Acts Chapter 219, Section 6. These changes represent the most substantial overhaul of Kentucky's child support guidelines in over a decade, affecting how support amounts are calculated, when modifications are available, and how medical expenses factor into obligations.
The four major changes are:
- Income cap doubled: The maximum combined monthly adjusted parental gross income increased from $15,000 to $30,000, meaning families earning a combined $360,000 per year now fall within the guidelines table rather than requiring judicial discretion for above-cap calculations
- Modification threshold lowered: A 10% change in the calculated support amount now constitutes a material change in circumstances, down from the previous 15% threshold, making it easier for parents to seek adjustments
- Extraordinary medical expense threshold reduced: The annual threshold for extraordinary medical expenses dropped to $100, meaning medical costs exceeding $100 per year are now factored into the support calculation rather than absorbed by the custodial parent
- Parenting time adjustments: Building on 2023 amendments (HB 501), support calculations now more precisely account for each parent's number of overnights, reducing the obligation for parents who exercise significant parenting time
These changes apply to all new child support orders entered after July 1, 2025, and serve as grounds for modifying existing orders when the recalculated amount differs by 10% or more from the current obligation.
Child Support Arrearages After the Child Turns 18
Unpaid child support in Kentucky does not expire when the child reaches age 18. Kentucky enforces child support arrearages for up to 15 years after the child reaches the age of majority under KRS 413.090, giving the custodial parent until the child's 33rd birthday to pursue collection. The total amount of arrearages plus statutory interest (currently 12% per year under KRS 360.010) can grow substantially if left uncollected.
Kentucky's Child Support Enforcement Division within the Cabinet for Health and Family Services provides collection assistance at no cost to the custodial parent. Enforcement tools include federal and state tax refund intercepts, wage garnishment of up to 65% of disposable income for obligors with arrearages, passport denial for debts exceeding $2,500, professional license suspension, credit bureau reporting, and contempt of court proceedings that can result in up to 6 months of incarceration per violation.
The paying parent cannot discharge child support arrearages through bankruptcy. Under 11 U.S.C. Section 523(a)(5), child support obligations are classified as non-dischargeable debts, meaning they survive Chapter 7, Chapter 11, and Chapter 13 bankruptcy proceedings. This federal protection ensures that past-due child support remains collectible regardless of the obligor's financial circumstances.

Frequently Asked Questions
At what age does child support end in Kentucky?
Child support ends at age 18 in Kentucky under KRS 403.213. If the child is still enrolled in high school at 18, support continues through the end of the school year in which the child turns 19. Kentucky does not extend support for college enrollment. The termination is automatic, but parents should file a motion to formally close the case and stop wage withholding.
Can child support continue past 18 if my child is in college in Kentucky?
No. Kentucky has no statute requiring parents to pay child support while a child attends college. Support terminates at age 18 (or 19 if still in high school) regardless of college enrollment. However, parents may voluntarily agree to contribute to college costs in their separation agreement under KRS 403.180, and such agreements become enforceable court orders.
How do I stop child support payments in Kentucky when my child turns 18?
File a motion to terminate child support with the Circuit Court in the county where your order was entered. The filing fee ranges from $115 to $250 depending on the county as of March 2026. Provide proof the child has reached 18 and is no longer in high school. Do not stop payments unilaterally; arrearages accrue until a court formally terminates the order.
Does child support end automatically in Kentucky or do I need a court order?
While the legal obligation technically ends when the child reaches the statutory age, wage garnishment and income withholding orders do not stop automatically. The paying parent must file a motion with the court and obtain a written termination order to stop payroll deductions. Until the court enters the order, the employer will continue withholding support from the obligor's paycheck.
What happens if my child drops out of high school before age 19 in Kentucky?
Child support terminates on the date the child withdraws from high school if the child has already turned 18. The high school extension under KRS 403.213(3) requires continuous enrollment. If the child drops out in October at age 18, support ends in October, not at the end of the school year. The paying parent should obtain proof of withdrawal and file it with the court.
Can child support be extended for a disabled child in Kentucky?
Yes. Kentucky courts may extend child support indefinitely for a child with a disability that existed before age 18 and prevents self-sufficiency. The custodial parent must file a motion with medical documentation before the existing order expires. Courts consider the disability's severity, the child's earning capacity, government benefits eligibility (SSI pays up to $943 per month in 2024), and both parents' financial resources.
What is the new 10% modification rule for Kentucky child support in 2025?
Effective July 1, 2025, Kentucky lowered the modification threshold from 15% to 10% under amended KRS 403.212. If the recalculated child support amount differs by 10% or more from the current order, either parent can petition for modification. The income cap also doubled from $15,000 to $30,000 in combined monthly income, potentially increasing support for higher-earning families.
Can back child support be collected after my child turns 18 in Kentucky?
Yes. Kentucky enforces child support arrearages for up to 15 years after the child reaches age 18 under KRS 413.090. Unpaid support accrues 12% annual interest under KRS 360.010. Enforcement tools include tax refund intercepts, wage garnishment up to 65% of disposable income, passport denial for debts over $2,500, and contempt of court proceedings.
Does getting married emancipate a child and end child support in Kentucky?
Yes. Marriage emancipates a minor child under Kentucky law and immediately terminates the child support obligation under KRS 403.213. Kentucky permits marriage at age 17 with parental consent under KRS 402.210. The paying parent should file the child's marriage certificate with the court and request a formal order terminating support.
How much does it cost to file for child support termination in Kentucky?
Filing a motion to terminate child support in Kentucky costs between $115 and $250 depending on the county as of March 2026. Fee waivers are available through a Motion for Waiver of Costs (In Forma Pauperis) for parents who cannot afford the fee. Verify the exact amount with your county's Circuit Court Clerk before filing. If the termination is contested, attorney fees typically range from $2,500 to $7,500.
